In the meantime, could you tell me if the CudaBridge can take advantage of some SLI configuration ? I know CUDA by itself will support it but it's up to applications to take advantage of multiple CUDA devices.

Did you get an answer kels, because your question is still unanswered in this thread I think.

11 is CPU, 15 is Cuda. Ok. But what is the difference between 14 cuda and 15 cuda?

And the Cuda FAQ states to only enable cuda for FREQD mode, and use the regular mode for OPTTIMED.

So I still see no answer to the question "does TIMED work on Cuda or not?".

BTW, I thought Cuda was only relevant if you used very long reverbs, and it would actually be a lot slower on 'simple' stuff like Pre's, EQ's, Tape, Dynamics, etc...

I tried enabling cuda on my (now sold) gtx660, and then tried it with the gtx760 I have now, but Reaper would render at 0.15 realtime with cuda, and 0.8 with pure CPU. It all depends on your libraries and settings you use ofcourse, but for me it seemed to be a lot slower instead of faster .
